Professor Yury Gogotsi has won the 2017 Energy Storage Materials Award, which is awarded by the journal Energy Storage Materials. The Award will be presented to Professor Gogotsi at the ICEnSM 2017 (2017 International Conference on Energy Storage Materials), which will be held in Shenzhen, China, on Nov. 18-21, 2017. The award, which is sponsored by Elsevier, gives special recognition to a person who has accomplished outstanding achievements in energy storage materials and devices.

It turns out that when they’re in a hurry and space is limited, ions, like people, will find a way to cram in — even if that means defying nature’s norms. Recently published research from an international team of scientists, including Drexel University’s Yury Gogotsi, PhD, shows that the charged particles will actually forgo their “opposites attract” behavior, called Coulombic ordering, when confined in the tiny pores of a nanomaterial. This discovery could be a pivotal development for energy storage, water treatment and alternative energy production technologies, which all involve ions packing into nanoporous materials.

In their paper, which was recently published in the journal Nature Materials, the researchers explain how Coulombic ordering in liquid salts starts to break down when ions are confined in small spaces — specifically carbon pores less than a nanometer in diameter. And the narrower the pore, the less the ions adhere to Coulombic ordering. Read the full press release here.

While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due to short-circuiting in mobile devices. In hopes of preventing more of these hazardous malfunctions researchers at Drexel University have developed a recipe that can turn electrolyte solution — a key component of most batteries — into a safeguard against the chemical process that leads to battery-related disasters.

Prof. Yury Gogotsi and Drexel students participate in the International Workshop on Energy, Environment, Water, and Sustainability (EEWS 2017) at KAIST on August 3, 2017. Prof. Gogotsi’s talk was titled, “2D Metallic Carbides and Nitrides (MXenes) and Advancement of Technology.“ View the full meeting program here.

Can you imagine fully charging your cell phone in just a few seconds? Researchers in Drexel University’s College of Engineering can, and they took a big step toward making it a reality with their recent work unveiling of a new battery electrode design in the journal Nature Energy.

The team, led by Yury Gogotsi, PhD,Distinguished University and Bach professor in Drexel’s College of Engineering, in the Department of Materials Science and Engineering, created the new electrode designs from a highly conductive, two-dimensional material called MXene. Their design could make energy storage devices like batteries, viewed as the plodding tanker truck of energy storage technology, just as fast as the speedy supercapacitors that are used to provide energy in a pinch — often as a battery back-up or to provide quick bursts of energy for things like camera flashes.

PhD Candidates, Kathleen Maleski and Christine Hatter, attend the NANO KOREA 2017 meeting in South Korea. Both students will continue their stay in South Korea by participating in our NNFC-Drexel Nano2 Co-op Center, collaborating with colleagues at NNFC-KAIST.

Congratulations to our team of our current and former students and post-docs led by Dr. Maria Lukatskaya on publishing a very important article that opens new avenues for high-rate, high-energy storage not only for MXenes, but for pseudocapacitive materials in general:
